TOPCon, short for Tunnel Oxide Passivated Contact, is a state-of-the-art solar cell technology. This innovative design represents a significant advance over conventional solar cell architectures and offers improved efficiency and performance that surpasses that of the widely used PERC (Passivated Emitter and Rear Cell) technology.
At the heart of TOPCon solar cells is a unique structure that uses a thin oxide layer and a polycrystalline silicon layer to create a highly efficient passivated contact. This design enables improved charge carrier extraction, resulting in higher energy conversion rates.
TOPCon cells are a type of n-type solar cell made from a phosphorus-doped semiconductor material, which contributes to their excellent performance.
One of the most important advantages of TOPCon solar cells is their higher efficiency compared to conventional solar cell technologies such as PERC.
